House design
We are now going to visit a few home builders and get some inspiration... because we cannot and do not want to change the orientation on the plot.

Attached are also the details of our financial situation
General about you:

[*]Who are you? Family of 3
[*]How old are you? 2x 37 + 1x 7
[*]Are children planned? completed
[*]What do you do professionally? He -> employee; She -> civil servant
[*]How many hours do you work? He -> full-time; She -> part-time

Income and asset situation:

[*]What income do you have (gross/net)? Total 5000€ including child benefit
[*]How much equity do you have? Plot worth 100,000€ + 100,000€ capital
[*]How much equity do you want to put into the house project? 100,000€

Expense situation:
Expenses already included in other items can of course be left out. This list is not exhaustive and can be extended or summarized at will. Please make sure to state all costs monthly, even if they only occur annually!

Housing costs:

[*]Current cold rent: 900€
[*]Current warm rent: 1200€
[*]Electricity: heating and living total 110€ per month
[*]Phone, internet, mobile: internet and mobiles total 45€ per month

Income and expense totals:

[*]Total income: 5000€
[*]Total expenses: approx. 4500€ (incl. all (savings approx. 1000€)
[*]Balance: + 500€ per month
[*]Of which cold rent sum: 900€ + 500€ surplus --> 1400€

Do you think it is realistic at all to build a house for a total of approx. 500,000€?
Our rough calculation would be as follows:

House construction costs approx. 150 sqm turnkey on slab: 375,000€
Carport/storage room: 25,000€
Additional costs: 40,000€
Outdoor facilities (garden/paving/terrace...): 50,000€

Total: approx. 500,000€

Thank you very much for your feedback :)

Name the development plan (Warning: without link!). I find it a bit crazy that the building envelope is indented equally (double garage width) where the garages are drawn in on the parcel plan.

Name the development plan (Caution: without link!).

So "Thalmassing 'an der Weilloher Straße'". I will take a closer look at it these days.

Has the floor plan somehow gone missing here? I can't see anything at all...

Morning,

unfortunately, that doesn’t exist yet... we first have to figure out how we can/want to do it with the slope.
